The tear trough deformity is a natural consequence of the anatomic attachments of the periorbital tissues. A variety of techniques have evolved to address this cosmetic issue including subtractive blepharoplasty techniques, elevation of ptotic eyelid and midface tissues, and the injection or implantation of autogenous or alloplastic materials to diminish its appearance. Greater anatomic understanding of the pathogenesis of the tear trough deformity has led to more anatomically conservative and appropriate cosmetic surgical treatments. The decline in purely subtractive surgical techniques in blepharoplasty surgery and the advent of fat-repositioning techniques and new subdermal fillers have improved surgical outcomes.
泪槽畸形是眼周组织解剖附着的自然结果。为了解决这个美容问题，已经发展出了各种技术，包括减法重睑术技术、下垂的眼睑和中面部组织的提升，以及注射或植入自体或同种异体材料来减轻其外观。对泪槽畸形发病机制的更深入解剖学理解导致了更具解剖学保守性和适当的美容手术治疗。在重睑手术中，纯粹减法手术技术的下降，以及脂肪复位技术和新型真皮填充剂的出现，改善了手术效果。
